I made a video on how to home a cnc without home switches, and how to use that in conjunction with the work offsets, safe Z, Z28 home, and more. This was very confusing to me when I started in cnc world, and probably confusing to most of us when we started. I hope it helps!

Very nice video thank you. I am really starting to grasp the whole home and offset strategy.
Where did you get the GUI? It looks nothing like the mach3 screens I'm used to.
Also I'm a little confused about the reason for setting machine coordinates in g53. If you sync G54 with the machine coordinates and soft limits aren't you accomplishing the same thing? Without having to ever type any commands? G54 then becomes a mirror of g53 and is the defacto home, you just burn the offset for other uses but there's plenty more to use.
Also my experience is that unless you have a power failure not allowing you to exit mach normally or move your machine manually after shut down that Mach does indeed remember exactly where the machine was when you stopped. Even if you turn off your PC. When I reboot and restart mach the machine coordinates are right where I left it and if I haven't moved the machine by hand no more re zeroing is needed after verifying. I am trying to get the habit of moving my machine to g54 home prior to shutdown that way even if by some chance machine coordinates boot up other than zero you can ref all home in g54 from that spot.
Since my machine has no hand wheels to move things with power off this seems to work pretty well.
